Abstract

The invention relates to metal water-based stamping liquid and a preparation method of the metal water-based stamping liquid. The metal water-based stamping liquid comprises the components by weight: 3-5% of lubricating extreme pressure agent, 2-4% of polyamide, 3-4% of triethanolamine, 0.1-0.2% of triazole fungicide, 0.1-0.5% of benzotriazole, 0.2-0.4% of hydroxypropyl methylcellulose, 0.05-0.1% of three-dimensional siloxane defoaming agent and the balance of distilled water. The preparation method comprises the main steps of: firstly, adding the distilled water, and then, orderly adding the lubricating extreme pressure agent, polyamide, triethanolamine, triazole fungicide, benzotriazole, hydroxypropyl methylcellulose and three-dimensional siloxane defoaming agent to mix. The action mechanism provided by the invention is simple and scientific; punch forming and anti-dusting effects of the metal achieve the optimal state by synergistic effect of the components; the water-based stamping liquid contains the triazole fungicide, so that decaying of the stamping liquid in storing and working processes can be effectively prevented; and the hydroxypropyl methylcellulose can assist film forming, and the fluid friction resistance is reduced, so that the water-based stamping liquid better protects the metal in the metal stamping and molding processes, and the anti-dusting time is more effectively increased after a workpiece is processed.

Description

A kind of water-base metal punching press liquid and preparation method thereof

Technical field

The invention belongs to the metal stamping field, especially a kind of water-base metal punching press liquid and preparation method thereof.

Background technology

Water-base stamping liquid is a kind of compound that is grouped into by multiple one-tenth such as water based lubrication extreme pressure agent, water-based antirusts, is mainly used in technologies such as punchless drawing in the Workpiece shaping process, punching, stamping-out, bending, and lubricity is good; Particularly cold true performance is good; Penetrating quality is good, and the rust prevention during manufacture time is long, and environmental pollution is little; Production safety is the direction of present punching press with the liquid development.But many in the market employing nitrite prepare water-base stamping liquid as rust-preventive agent; This kind rust-preventive agent contains carcinogenic substance; Human body directly contacts and causes skin carcinoma easily, and is prone to more residual rust-preventive agent formation white dots in the metallic surface, and rust-proof effect is relatively poor.

Through retrieval, do not find the publication document identical as yet with present patent application.

Summary of the invention

The objective of the invention is to overcome the weak point of prior art, long, lubricated good cooling results of a kind of green non-poisonous, antirust time, water-base metal punching press liquid safe in utilization and preparation method thereof are provided.

The objective of the invention is to realize through following technical scheme:

A kind of water-base metal punching press liquid, its moity and weight percent are:

Lubricated extreme pressure agent 3-5%;

Multiamide 2-4%;

Trolamine 3-4%;

Benzotriazole 0.1-0.5%;

Vltra tears 0.2-0.4%;

Triazines sterilant 0.1-0.2%;

Three-dimensional type siloxane skimmer 0.05-0.1%;

All the other adding distil waters to 100%.

Wherein, said lubricated extreme pressure agent is the lubricated extreme pressure agent of sulfur-bearing, phosphorus extreme pressure element.

A kind of preparation method of water-base metal punching press liquid, the step of preparation is following:

⑴ add zero(ppm) water in the reaction kettle, adds lubricated extreme pressure agent again and stir;

⑵ add multiamide, trolamine successively in reaction kettle, stir to complete miscibility;

⑶ add benzotriazole in the question response still during liquid phase transparent and homogeneous, add Vltra tears again after being stirred to whole dissolvings, be stirred to Mierocrystalline cellulose and all dissolve;

⑷ add the triazines sterilant at last, three-dimensional type siloxane skimmer is stirred to homogeneous transparent and gets final product.

Advantage of the present invention and positively effect are embodied in:

The simple science of the mechanism of action of the present invention, the synergy through each component make the impact briquetting of metal and rust-proof effect all reach best, select advanced water-based antirust for use---multiamide replaces nitrite, except rust-proof effect better, also environmental protection more; Contain sterilant in the water-base stamping liquid; It is corrupt to prevent effectively that punching press liquid from taking place in storage and working process; Vltra tears can be assisted film forming; And reduce the fluid friction resistance, and make water-base stamping liquid better protection metal in metal stamping formed process, more effectively improve the antirust time after the workpiece processing.

Compare with traditional punching oil, advantage is:

1,----cooling performance of the present invention is superior to traditional punching oil to have increased die life, in the process of using, has reduced the press work temperature, makes mould obtain better protection.

2, reduced the traditional punching oil of cost of raw and processed materials----and belonged to full oil type product, cost an arm and a leg, and be difficult for cleaning, workshop section uses clean-out system to make it to remove in the back, increases raw-material consumption once more; The present invention is soluble in water, and available clear water is directly cleaned, and has reduced the consumption of clean-out system, simplifies working process, and shortens the PT, raises the efficiency, and brings huge energy conservation to whole process of production.

3, High-efficient Production----can be cooled off workpiece and punching press lathe rapidly in using process of the present invention, increase drawing velocity, increases work efficiency.

4, the present invention of protection environment----replaces traditional punching oil, can reduce the greasy dirt of press workshop, greatly improves workshop condition; Simultaneously, the present invention all selects the environment-friendly type raw material for use, and the responsibility of industrial discharge alleviates greatly.

5, security----the present invention of raising production plant is complete synthesis type punching press liquid, does not contain MO and vegetables oil, and is safe in utilization, the possibility of the exhausted acomia calamity of lighting a fire, and for traditional punching oil, SF improves greatly.
